posix_spawnattr_getsigdefStandard C Library Fposix_spawnattr_getsigdefault(3C)NAME
posix_spawnattr_getsigdefault, posix_spawnattr_setsigdefault - get and
set spawn-sigdefault attribute of spawn attributes object
SYNOPSIS
#include <signal.h>
#include <spawn.h>
int posix_spawnattr_getsigdefault(const posix_spawnattr_t *restrict
attr, sigset_t *restrict sigdefault);
int posix_spawnattr_setsigdefault(posix_spawnattr_t *restrict attr,
const sigset_t *restrict sigdefault);
DESCRIPTION
The posix_spawnattr_getsigdefault() function obtains the value of the
spawn-sigdefault attribute from the attributes object referenced by
attr.
The posix_spawnattr_setsigdefault() function sets the spawn-sigdefault
attribute in an initialized attributes object referenced by attr.
The spawn-sigdefault attribute represents the set of signals to be
forced to default signal handling in the new process image (if
POSIX_SPAWN_SETSIGDEF is set in the spawn-flags attribute) by a spawn
operation. The default value of this attribute is an empty signal set.
RETURN VALUES
Upon successful completion, posix_spawnattr_getsigdefault() returns 0
and stores the value of the spawn-sigdefault attribute of attr into the
object referenced by the sigdefault parameter. Otherwise, an error
number is returned to indicate the error.
Upon successful completion, posix_spawnattr_setsigdefault() returns 0.
Otherwise, an error number is returned to indicate the error.
ERRORS
These functions may fail if:
EINVAL The value specified by attr is invalid.
The posix_spawnattr_setsigdefault() function may fail if:
EINVAL The value of the attribute being set is not valid.
